Five different companies (G, J, S, O, U) compete each year to be the sole supplier of relays to a major automobile manufacturer. Supplier G J S O U probability .15 .04 .01 .55 .25 Given that suppliers O and U are both ultimately not chosen, what is the probability that supplier S will be chosen

The probability is

Step-by-step explanation:

From the question we are told that

  The probability of each company to be chosen is

            Supplier               G           J           S           O             U

            Probability           0.15     0.04     0.01       0.55       0.25

Generally the probability that company  G , J  ,  S are chosen is  

=>    

Generally the probability that company  O, U are chosen is  

=>  

Generally  the probability that supplier S will be chosen given that suppliers O and U are both ultimately not chosen is mathematically represented as

And  

=>  

=>  

1/800 is the right answer
